International Comfort Products NDN5100BFA1 Control Board
Your air handler will be unable to be able to function without the main control board installed. The International Comfort Products NDN5100BFA1 control board is constructed to operate the gas valve, the igniter, all the various sensors and the blower all at once. You should always be careful when you are deciding on a replacement because of the many variances of models and types. The chosen circuit board should match the model number with both the make and model of HVAC system.
